Overview

CalypsoAI provides guardrails for generative AI applications, and now operates as part of F5, delivered as F5 AI Guardrails. That acquisition context matters: it places AI security inside an established application-delivery and security vendor rather than a standalone startup, which changes both the integration story and the procurement path.

The problem is specific to deployed AI. An application built on a language model is exposed to prompt injection, data leakage through responses, and harmful output under adversarial input, none of which conventional application security controls address. Guardrails sit between the model and the user to enforce policy at runtime.

Covering pilot through to production is the right scope, because most organisations discover these problems only after a pilot becomes something customers use. Being part of F5 means it fits into infrastructure many enterprises already run, which is a real practical advantage over point solutions.

Key features

  • Runtime guardrails between the model and the user
  • Protection against prompt injection and data leakage
  • Policy enforcement across cloud deployments
